///An atheist says to a believer that they have an interesting idea there, but I want to see evidence as I don't tend to rely on faith, thanks. I can't dismiss your idea for certain////

That's not an atheist; that's an agnostic.

And an agnostic, having declared that he can't say for certain, can then go ahead and believe (just for himself) that there is a god. OR he can go ahead and believe (just for himself) that is is NO god. In either case, he can't prove it, and admits it--and goes further, that he believes that NO ONE can prove either proposition, even though he chooses to believe one or the other.
